Facebook App Error Message: redirect_uri URL is not properly formatted
If you get an error when you want to add a Facebook Page app to your facebook fan page, like this:
An error occurred with websitewelcometest. Please try again later.
API Error Code: 100
API Error Description: Invalid parameter
Error Message: redirect_uri URL is not properly formatted
The proper way was to use a url with the api id + the base url.
But it doesn’t work sometimes.
The workaround that worked for me was to replace the baseurl with facebook.com – (leaving it out completely didn’t work).
This is the new URL that I used which worked:
(copy/paste that url, but change the “App_ID” # to YOUR “App_ID” for it to work (just make sure you leave the facebook.com url address at the end, exactly as it’s written above)
And good news for those who have created a separate App Page for their Facebook Page (via the Advanced Settings in your App).. if you have done that, Facebook has announced a few days ago, that it now has an “Add App to Page” option which might make things a little easier (I’d rather use the URL and not create a separate page for each of my apps because I make so many of them, but people who are just using these for just their own fan page will probably love this new feature!)
